Side scraper reclaimer is widely used in cement, building material, coal, power, metallurgy chemical and other industries, it can homogenize a variety of materials, such as bauxite, clay, iron ore, raw coal and other materials with different types and densities, and preblending them in the same stockyard to meet the requirements of different working conditions. Thus, the production process and operation of users are simplified, the technical and economic indexes are improved, and greater economic benefits are obtained. The side scraper reclaimer products of our company have been updated several times. Its arm length range is 11-36m, and the reclaiming capacity range is 30-700t / h. The equipment has unattended function, and the stockyard can realize one key pile change. This equipment has strong adaptability to materials, especially the reclaiming function of side scraper can fundamentally solve the problem of scraping sticky and wet materials.
The side scraper reclaimer is mainly composed of walking end beam, frame, winch system, scraper reclaiming system, support frame, lubrication system, track system control room and other components.
·Adopt advanced design methods, such as computer-aided design, three-dimensional design and optimization design of steel structure. Absorbing advanced technology, together with the experience of designing and manufacturing stacker reclaimer and continuous summary and improvement, we can achieve advanced and reasonable technology and reliable equipment use in the design.
·Advanced production equipment and technological means are adopted to ensure that, for example, the steel pretreatment production line can ensure the improvement of the quality and corrosion resistance of the manufactured products, and the use of large milling and boring machines improves the processing quality of large parts. The whole assembly of large components is performed in the factory, the driving part is tested in the factory, and the rotary part is made by mold.
·Use new materials, such as wear-resistant materials and composite materials.
·External accessories adopt advanced products at domestic and abroad.
·The equipment is provided with various protective measures.
·Advanced testing means and strict quality management system.

Compilation：
Spare parts grading: Grade A - key wearing parts, which will cause huge losses due to failure and shutdown. It is recommended to keep 1-2 sets in reserve; Grade B - regularly replaced parts, combined with maintenance cycle reserves. The specific models, specifications and interchangeability must be subject to the drawings, nameplates and operating manuals of the final equipment manufacturer. This list is a summary of commonly used parts.
